[pve-devel] [PATCH manager v3 08/10] ceph: gui: rework pool input panel

[Alwin Antreich <a.antreich@proxmox.com>]

* add the ability to edit an existing pool
* allow adjustment of autoscale settings
* warn if user specifies min_size 1
* disallow min_size 1 on pool create
* calculate min_size replica by size
